We look at the division of 531556 by 15 
Our goal is to divide 531556 by 15.

Moving on to step 1:
If we divide 5 by 15, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 15

Going ahead to step 2:
The number 15 fits into 53 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 45 from 53 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 15

On to step 3:
15 can be fit into 81 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtracting 75 from 81 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 15

On to step 4:
If we divide 65 by 15, we get 4 and a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 354.0
The remainder is 5 after subtracting 60 from 65.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 15

Going ahead to step 5:
55 divided by 15 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3543.0
If we take 45 away from 55, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 15

Step 6:
15 goes into 106 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 35437.0
If we take 105 away from 106, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
15 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 35437.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 35437.06
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 35437.066
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 35437.066 and a remainder of 0.001.
